Summary
Tammany, Louisiana, is a privately owned earth dam completed in 2004 for fire protection, stock, and small fish pond purposes. Standing at a height of 9 feet with a hydraulic height of 6 feet, the dam spans 380 feet in length and has a storage capacity of 72 acre-feet. The dam is regulated by the Louisiana Department of Transportation and Development, with state permitting, inspection, and enforcement in place to ensure its safety and compliance.
Although Clark Branch Dam has a low hazard potential and is assessed to be in fair condition, with a moderate risk rating, emergency preparedness and risk management measures remain unspecified. The dam features an uncontrolled spillway with a width of 40 feet, serving the TR-Clark Branch stream. Despite its limited drainage area of 0.31 square miles, the dam plays a crucial role in mitigating floods and providing water resources to the surrounding area.
Water resource and climate enthusiasts will appreciate the engineering aspects of Clark Branch Dam, from its soil foundation to buttress core design. With a focus on safety and functionality, the dam serves as a vital infrastructure for the community, highlighting the importance of responsible dam management in the face of changing climatic conditions.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
